Summary

Kansas City caps short-term rentals at one per parcel: if your lot has just one principal dwelling unit, you can rent out either that home or a backyard accessory dwelling unit as a short-term rental, but not both at once.

Short-term rental limitation for parcel with one principal dwelling unit. Any parcel with only one principal dwelling unit shall be allowed to have only one short-term rental, regardless of whether the short-term rental is in the principal dwelling unit or an accessory dwelling unit on such parcel. In this subsection, the terms "principal dwelling unit" and "accessory dwelling unit" shall have the same meanings as provided in chapter 88 of this Code.(6)Prohibition for short-term rentals that would qualify for deregistration. Any proposed short-term rental that would, if it were registered, otherwise qualify for deregistration pursuant to section 56-804 shall be ineligible for registration.(7)Determination to issue or renew registration. Upon the director's determination that the requirements of this section have been satisfied, the director shall issue to the registrant a unique registration number for the dwelling unit. Each registration issued under this article shall expire at the end of its registration period and shall be subject to renewal annually. Any renewal registration must comply with all requirements of this section, and will be accepted beginning 30 days before the end of the previous registration period and may be made without penalty before the end of the previous registration period. (Ord. No. 250965, § 1, 11-13-25)

Full Breakdown

City Code § 56-803(5) limits any parcel carrying only one principal dwelling unit to a single short-term rental registration, whether that registration covers the principal house or an accessory dwelling unit on the same lot. Owners can't register both the main home and a backyard ADU as separate short-term rentals simultaneously: only one dwelling unit on the parcel may hold an active registration at a time. The neighborhood services department administers registration under section 56-803, and 'principal dwelling unit' and 'accessory dwelling unit' carry the definitions set in the Zoning and Development Code, chapter 88.

Violations & Fines

Registering or operating a second short-term rental on a parcel with only one principal dwelling unit violates section 56-803(5); the city can deny, revoke, or refuse to renew the registration and cite the property under chapter 56.

Frequently Asked Questions

Can I rent out my ADU as an Airbnb if I also rent the main house?
No. Kansas City allows only one short-term rental per parcel under Sec. 56-803(5): you must choose either the principal home or the accessory dwelling unit, not both at the same time.
Does this rule apply if my ADU is the only rental and I live in the main house?
No: the cap counts against the parcel, not the resident. If the main house isn't itself a registered short-term rental, you can register the ADU alone as your one permitted short-term rental.
